[be] Change validate functions to not return unnecessary Result

These validations needs to be able to transitively check for violations within 
function expressions, without immediately erroring. So the inner "-Impl" helpers 
return a Result. But the outer, exported validate functions don't need to return 
a Result, especially since TS has no Rust-style enforcement that return values 
are actually used. Unwrapping within the validation means the caller can't 
forget to do so and inadvertently silence the errors.
